Description

These signals can be found in LogiCORE IP Tri-Mode Ethernet MAC v5.1, page 12, of the DS818 document.

Solution

The tx_reset and rx_reset outputs from the MAC are based on the respective software resets, so theyare active when this reset bit is set (i.e Receiver Configuration Word 1 (0x404) - Bit 31). They are also active when either the global reset input is active (low) or the domain specific axi reset is active (i.e rx_axi_rstn, DS818 - page12).

The purpose of these outputs is to allow connected logic to be reset at the same time as the MAC.
